Details

In the Linux kernel, the following vulnerability has been resolved:

binder: fix memleak of proc->delivered_freeze

If a freeze notification is cleared with BC_CLEAR_FREEZE_NOTIFICATION before calling binder_freeze_notification_done(), then it is detached from its reference (e.g. ref->freeze) but the work remains queued in proc->delivered_freeze. This leads to a memory leak when the process exits as any pending entries in proc->delivered_freeze are not freed:

This patch fixes the leak by ensuring that any pending entries in proc->delivered_freeze are freed during binder_deferred_release().
